C3850 Stack ports blinking amber after upgrade to 16.09.07

[BorislavPenchev0962]

 Hi all,

we were on IOS Version16.09.3a and did upgrade to 16.09.07.
2x WS-C3850 (no PoE)Switches in stack with 4x10G SFP Uplinks
All Ports are connected and STP FWD state, but blinking amber, beside that no performance issues ?

we checked as per port LED mode documentation and Switch election is fine

  all Ports – exc SFP blink amber which is error state ?

Regards

Borislav

you mention 4x10G uplink but your output shows 8x Tex/x/x ports (Te->10G)
-> either the ports (Gi x/x/x?)   are not detected correctly, 
or the blinking amber tells you the port is nut running at 10G, but at lower speed , which is no problem, just informative LED status 
-> post output from "show interface status" to confirm

C3850 Stack ports blinking amber after upgrade to 19.09.07  

Please confirm is this the correct version?

Looks for me some cosmetic bug, do you have old config before upgrade ? can you compare the config before and after upgrade ?
